degrees() and radians() in Python

degrees() and radians() are methods specified in math module in Python 3 and Python 2. 
Often one is in need to handle mathematical computation of conversion of radians to degrees and vice-versa, especially in the field of geometry. Python offers inbuilt methods to handle this functionality. Both the functions are discussed in this article.

radians()

This function accepts the “degrees” as input and converts it into its radians equivalent. 

Syntax : radians(deg) Parameters : deg : The degrees value that one needs to convert into radians Returns : This function returns the floating point radians equivalent of argument. Computational Equivalent : 1 Radians = 180/pi Degrees.

Code #1 : Demonstrating radians() 

Python3

# Python code to demonstrate
# working of radians()

# for radians
import math

# Printing radians equivalents.
print("180 / pi Degrees is equal to Radians : ", end ="")
print (math.radians(180 / math.pi))

print("180 Degrees is equal to Radians : ", end ="")
print (math.radians(180))

print("1 Degrees is equal to Radians : ", end ="")
print (math.radians(1))

Output:

180/pi Degrees is equal to Radians : 1.0
180 Degrees is equal to Radians : 3.141592653589793
1 Degrees is equal to Radians : 0.017453292519943295

degrees()

This function accepts the “radians” as input and converts it into its degrees equivalent. 

Syntax : degrees(rad) Parameters : rad : The radians value that one needs to convert into degrees. Returns : This function returns the floating point degrees equivalent of argument. Computational Equivalent : 1 Degrees = pi/180 Radians.

Code #2 : Demonstrating degrees() 

Python3

# Python code to demonstrate
# working of degrees()

# for degrees()
import math

# Printing degrees equivalents.
print("pi / 180 Radians is equal to Degrees : ", end ="")
print (math.degrees(math.pi / 180))

print("180 Radians is equal to Degrees : ", end ="")
print (math.degrees(180))

print("1 Radians is equal to Degrees : ", end ="")
print (math.degrees(1))

Output:

pi/180 Radians is equal to Degrees : 1.0
180 Radians is equal to Degrees : 10313.240312354817
1 Radians is equal to Degrees : 57.29577951308232

Application : There are many possible applications of these functions in mathematical computations related to geometry and has a certain applications in astronomical computations as well.
